The Basic Introduction about Auto Air Condenser

The function of the condenser is to convert the high-temperature and high-pressure gaseous refrigerant sent by the compressor into a liquid refrigerant, and the refrigerant is dissipated in the condenser, and the state changes. Therefore, the condenser is a heat exchanger that dissipates the heat absorbed by the refrigerant in the vehicle to the atmosphere through the condenser.

 

The condenser of a small car is usually installed in the front of the car (usually installed in front of the radiator), and it is cooled by a fan (the condenser fan is generally shared with the radiator fan, and some models use a dedicated condenser fan).

 

The condenser is mainly composed of pipes and fins and has an inlet and a refrigerant outlet.

 

 

How does it work?

 

The refrigerant enters the evaporator, the pressure is reduced, and the high-pressure gas becomes a low-pressure gas. This process needs to absorb heat, so the surface temperature of the evaporator is very low, and then the cold air can be blown out by the fan. The high pressure and high-temperature refrigerant from the compressor are cooled to high pressure and low temperature. Then it is vaporized by a capillary tube and evaporated in the evaporator.

 

Classification of auto air condenser

 

According to the different types of cooling media, condensers can be classified into four categories, and their functions are as follows:

 

✔️Evaporative-Condensing:

 

In this type of condenser, the cooling effect generated by the evaporation of the refrigerant in another refrigeration system is used to cool the refrigerant vapor on the other side of the heat transfer partition and promote the condensation and liquefaction of the latter. Such as the evaporative condenser in cascade refrigerators.

 

✔️Air-cooled:

 

In this type of condenser, the heat given off by the refrigerant is carried away by air. The air can be natural convection or forced flow using a fan. This type of condenser is used for Freon refrigeration equipment in places where water supply is inconvenient or difficult.

 

✔️Water-cooled:

 

In this type of condenser, the heat given off by the refrigerant is carried away by the cooling water. Cooling water can be used for one-time use or recycled. Water-cooled condensers can be divided into vertical shell and tube type, horizontal shell and tube type and casing type according to their different structural types.

 

✔️Water-air cooling:

 

In this type of condenser, the refrigerant is cooled by water and air at the same time, but mainly relies on the evaporation of cooling water on the surface of the heat transfer tube, and absorbs a large amount of heat from the refrigerant side as the latent heat of vaporization of water. The role of air is Mainly to take away water vapor to speed up the evaporation of water. Therefore, the water consumption of this type of condenser is very small, and it is the preferred type of condenser for areas with dry air, low water quality, low water temperature, and insufficient water. This type of condenser can be divided into two types: evaporative type and shower type according to their different structures.
